We're looking at roughly 500 pieces as teh starting point for these, and the 83 by 47 by 10mm size fits nicely in a small parts drawer or even a pocket for quick jobs.
What it basically does is open split rings without you having to use your fingernails or risk bending them out of shape—the spring-loaded mechanism lets you work one-handed, which is pretty much essential when you're holding a jump ring in the other hand.

The high carbon steel with nickel-iron plating holds up better than the cheaper zinc alloy versions you'll see, and the chrome finish (yellow or custom) actually resists tarnish from daily use around oils and moisture.
Most buyers go with the 10mg—wait, wrong product—anyway, textured grip handles are comfortable enough for a full afternoon of jewelry repair, though it's not suited for heavy-gauge wire or anything above 2mm thick.

Lead time is usually 20 days or so form order, and our company can do OEM/ODM if you want your brand on the handle (check sample availability first, as we typically have stock for that).
One thing you wouldn't think to ask is that the spring tension is adjustable on these, so if it feels too stiff out of the box, you can loosen it slightly without tools.
MOQ is 500 pieces, but we do offer samples before you commit to a bulk order. Just reach out, and we'll arrange a sample for you.
